Review: JkDefrag v3.26

It is such a joy when I find great tools out in the public domain. Recently I discovered JkDefrag v3.26 - a tool for defragging your harddisks. It comes with a commandline version as well as screen saver and gui versions. This great program is free for the download and doesn't even contain an install program - which is great for booting from a thumb drive and running it. The screen saver version can start up a different screen saver when it completes, for those who don't want to give up a beloved other screen saver.
